| There was a previous radiation study of ricin, a dimeric molecule linked by a single disulfide bridge. |
| There is currently no antidote to ricin poisoning, but people exposed to moderate doses have recovered. |
| The assumption is that if ricin were weaponized, it would be treated like anthrax spores and dispersed for maximum effect. |
| Inside the flat, police found traces of ricin, castor oil beans and equipment for crushing the beans. |
| Because castor beans are readily available, public health officials warn that ricin could be used for terrorism. |
| Signs and symptoms of ricin poisoning depend on whether a person inhales or ingests ricin. |
